Definitions

  • the invention relates to an injector for filling an annular space formed around an anchor bolt, a fastening arrangement with such an injector, a container with such an injector and a method for installing an armature using such an injector.
  • the annular space which is formed around the anchor bolt anchored in a hole mechanical anchor, in particular expansion anchor, to fill with a filling material which cures in the annulus.
  • the armature can be supported in the radial direction in the hole and also in the attachment, which can improve the load values.
  • the filling of the annulus takes place from the center of the hole ago, namely by a filling channel formed in the anchor bolt.
  • the nozzle of an injection device is sealingly attached to the filling channel and filling compound filled into the filling channel.
  • the filled filling material exits through a transverse hole in the bolt.
  • the filling of the annular space via a washer with a through hole, where an injection device is attached takes place.
  • This single-portion Scheibeninjektor has a piston disc with a through hole for the anchor bolt and an upstream of the piston disc amount of a filling compound, wherein the piston disc forms a piston for displacing at least a portion of the amount of filling material in the annular space.
  • the injector is placed around the anchor bolt like a washer. When setting the anchor, the piston disc is pressed against the substrate and in this case at least a portion of the amount of filling material is pressed into the annular space around the anchor bolt around.
  • each filling for a single hole and since the injectors each have a washer-like piston disc, such an injector may also be referred to as a single-portion Scheibeninjektor.
  • the EP 2597322 A2 relates to a threaded part, in particular a screw or nut.
  • the thread of the threaded portion is provided with a coating containing microcapsules, at least a portion of the microcapsules containing a polymerizable adhesive.
  • an unsaturated methacrylate can be used as adhesive for the generation of the adhesive effect.
  • the hardener used in this case is a free-radical former, in particular a peroxide, which initiates the radical polymerization of the methacrylate.
  • the object of the invention is to provide a particularly simple and quick to use and at the same time cheap and reliable injector for filling an annular bolt formed around an anchor bolt, wherein the injector in particular has a particularly good storage stability and allows a particularly high performance of the set anchor, and further to provide a mounting assembly with such an injector, a container with such an injector and a method for installing an anchor using such an injector.
  • an injector for filling an annular space formed around an anchor bolt with a piston disc, which has a passage opening for the anchor bolt, and an upstream of the piston disc amount of a particular curable filling material, wherein the piston disc a piston for displacing at least one Forming part of the amount of the filling material in the annulus, wherein the filling material comprises a resin component containing as curable ingredient at least one free-radically curable resin, and a present in the form of microcapsules hardener component containing at least one curing agent for the radically curable resin of the resin component ,
  • the invention has recognized that in a single-portion disc injector in comparison to other types of injectors special boundary conditions can be given.
  • the receiving space for the filling compound is often comparatively small.
  • the mixing effect of the injector on the filling material is often comparatively low, since relatively short flow paths are given, which often do not allow multi-stage mixer arrangements.
  • the invention has further recognized that these particular constraints may limit the performance of conventional formulations and arrangements of the fill mass under some circumstances.
  • a two-component epoxy adhesive with layered components is used with regard to the small receiving space of the injector, it will often be necessary to select a layer sequence with comparatively thin layers. Because usually in view of the relatively low mixing effect, as they typically have single-portion Scheibeninjektoren, only with comparatively thin layers useful mixing and thus a useful for the performance of the set anchor hardening behavior of the epoxy adhesive can be obtained. With such a reduction of the layer thickness, however, an undesirable decrease in storage stability often accompanies. Because small layer thicknesses usually contain correspondingly large contact surfaces with the other component, but also with the environment. Due to the low stability, a layered arrangement of the components, in particular in the case of free-radically curing adhesives, is frequently scarcely possible. Because with conventional free-radically curing adhesives, so many radicals in the hardener component often form even at low temperatures that it would come to premature crosslinking of the resin component due to the proximity to the resin component, which is inevitably given in a layered arrangement.
  • the invention comes in and provides a composition and arrangement of the filling compound, which is particularly well suited in view of the boundary conditions, which sets up a single-portion Scheibeninjektor.
  • the invention provides for the use of a free-radically curing resin component into which a microencapsulated hardener component is incorporated. By means of the microencapsulation, premature contact of the radicals from the hardener component with the resin with corresponding adverse effects on the storage stability can be avoided in a particularly simple and effective manner.
  • the comparatively simple mixer arrangements of single-portion disk injectors are also sufficient here to ensure good curing behavior to achieve.
  • curable fillers available, which are particularly well suited for the regularly comparatively simple mixer assemblies of single-portion Scheibeninjektoren and here allow a particularly good curing behavior.
  • the fillers are particularly storage stable, despite the fact that the comparatively compact designs of single-portion Scheibeninjektoren often associated with a particularly close contact of the components of the fillers.
  • the filling compound forms a flowable, hardenable mass, which can be displaced fluidly from the injector into the annular space around the armature and hardens in the annular space.
  • the hardener component is microencapsulated, that is it is in the form of microcapsules. This may preferably be understood in the usual way in the art that the hardener component is present in the smallest portions in which it is immobilized by means of at least one wrapping material.
  • a core-shell encapsulation may be provided, in which the hardener component is enveloped by the shell material, so that capsules are each provided with at least one shell.
  • the microcapsules containing the hardener component are embedded in the filling compound in the resin component, that is to say the resin component forms a matrix which contains the microencapsulated hardener component distributed.
  • the resin component and the hardener component of the filling compound are separated from each other by the shell material of the microcapsules, so that no reaction of the hardener component with the resin component takes place during storage and before displacement of the filling compound from the injector into the annular space.
  • the microcapsules are opened so that the curing agent can henceforth act on the resin. As a result, the curing of the resin is started.
  • the mechanically opening microcapsules should preferably not be too small, as this can ensure that the capsules are opened before they enter the annulus, so that a particularly effective curing process is given.
  • the resin is polymerizable by means of the curing agent, which causes the curing of the filling compound.
  • the resin component may also contain further constituents, for example an accelerator or a filler.
